The funds are a deferred loan which must be paid back upon sale or refinance. Upon such event the funds must be reimbursed at the same % of investment. For example, if DCHP invests 20% for downpayment of your home, they'll get 20% back whether or not your home appreciates.
Eligible parties include:
First-Time Homebuyers and persons who have not owned a home in the previous 3 years, single parents that have owned prior with a spouse, and displaced homemakers.
